Those are rugged plants, I can tell you that!
I have three little stalks that I got as a present at work. Didn't think they'd last long since they were cut stalks so I put them in a vase with about 3 inches of aquarium stones and water, then put them in my bathroom with no direct light. (again, didn't expect much from them) 2 1/2 years later they're taller than my vanity and still going strong.
Of course, looking it up quickly, apparently they like stones in water and indirect light...so maybe I didn't put them in such a bad place after all.
